I met the farmer at this one, he told me that some men from the village of Doon or Dun Bleisce (this is funnily enough is what it is called when u enter the village but on the OS map it is only called Dún) had tried digging around these stones looking for a tunnel which lead from them down to the bridge at the river below. He also mentioned something about a road leading the same way. He told me a local man in Doon tommy carew knows more about them.
